I'm reminded of the illustrious Bob Ross, that super laidback hippy painter guy that could produce a mountain top snow scene in minutes. He said it best and he said it right:

"Gotta have opposites, light and dark, in painting. It’s like in life. Gotta have a little sadness once in a while so you know when the good times come. I’m waiting on the good times now."

He was right, life would make no sense if it was good all the time, ups and dows give it meaning!
Keep trucking!
